The Hindu milk miracle was a phenomenon, considered by many Hindus as a miracle, which started on September 21, 1995, in which statues of the Hindu deity Ganesha allegedly 'drank' milk offerings. It attracted great attention from people and the media, particularly in India.
Before dawn on September 21, 1995, a Hindu worshipper at a temple in south New Delhi made an offering of milk to a statue of Ganesha. When a spoonful of milk from the bowl was held up to the trunk of the statue, the liquid was seen to disappear, apparently taken in by the idol. Word of the event spread quickly, and by mid-morning, it was found that statues of the entire Hindu pantheon in temples all over India were taking in milk.
By noon the news had spread beyond India, and Hindu temples in the United Kingdom, Canada, UAE, and Nepal among other countries had successfully replicated the phenomenon,
The reported miracle had a significant effect on the areas around major temples; vehicle and pedestrian traffic in New Delhi were dense enough to create a gridlock lasting until late in the evening. Many stores in areas with significant Hindu communities saw a massive jump in sales of milk, with one Gateway store in England selling over 25,000 pints of milk, and overall milk sales in New Delhi jumped over 30%.
Seeking to explain the phenomenon, Ross McDowall from India's Ministry of Science and Technology traveled to a temple in New Delhi and made an offering of milk containing a food coloring. As the level of liquid in the spoon dropped, the scientists hypothesized that after the milk disappeared from the spoon, it coated the statue beneath where the spoon was placed. With this result, the scientists offered capillary action as an explanation; the surface tension of the milk was pulling the liquid up and out of the spoon before gravity caused it to run down the front of the statue.
